[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] like Figure 1 and Figure 2As shown, the utility model provides a tooling for upper and lower parts of a tower crane standard segment for a powder coating line. The tower crane standard segment 10 is a triangular structure formed by a main chord 11 and two connecting rods 12. The tooling includes: a base 20 and a plurality of support rods 30; the base 20 is a rectangular frame structure; the plurality of support rods 30 are divided into two groups, and the two groups of support rods 30 are respectively vertically arranged on two opposite side edges of the base 20, and the support rods 30 on the two side edges are evenly spaced and aligned with each other; the main chord 11 of the tower crane standard segment 10 is set on the two side edges of the base 20 and abuts against the bottoms of the two support rods 30 on the two side edges, and the two support rods 30 respectively support two connecting rods 12 to position the tower crane standard segment 10. The utility model solves the problems of low coating efficiency and poor quality of the tower crane standard segment in the powder coating line in the prior art.

[0028] As an optimization solution of the utility model, Figure 1 and Figure 2 As shown, there are four support rods 30, and two support rods 30 are vertically arranged on two opposite side edges of the base 20, and the support rods 30 on the two side edges are evenly spaced and aligned with each other. It should be noted that the four support rods 30 are used as a preferred embodiment, and one tool can simultaneously hoist two standard segments to improve the efficiency of powder spraying of standard segments. The setting of four support rods 30 takes into account both cost and efficiency, but according to different process conditions and process conditions, the base 20 can be further increased and then the number of support rods 30 can be increased, such as setting six, eight, ten, etc. It should be noted that the number of support rods 30 needs to be an even number so that the support rods 30 can be evenly distributed on the two side edges.

[0029] As an optimization solution of the utility model, Figures 1 to 3 As shown, a support angle steel 31 is provided on the lower side of each support rod 30, and the two sides of the support angle steel 31 are in contact with the lower side of the support rod 30. Preferably, the support angle steel 31 is an L-shaped equilateral angle steel, and the two sides of the support angle steel 31 are respectively in contact with the two sides of the lower side of the support rod 30, and the concave surface of the support angle steel 31 is opposite to the lower side of the support rod 30, and a triangular structure is formed. This design exposes the convex surface of the support angle steel 31 to the outside, and when the tower crane standard segment 10 is in contact with the support angle steel 31, the tower crane standard segment 10 only contacts the corner edge line of the support angle steel 31, reducing the contact surface with the tower crane standard segment 10, reducing the subsequent paint repair area, and improving the product coating quality.

[0030] As an optimization solution of the utility model, Figures 1 to 3As shown, a gap is left between the bottom of the support angle steel 31 and the bottom of the support rod 30 to allow the steel particles to flow out during the shot blasting process. Preferably, the bottom of the support angle steel 31 and the bottom of the support rod 30 are not welded, because the tower crane standard segment 10 needs to be shot blasted before painting. If the bottom is welded, the steel particles will be stuck in the gap between the concave surface of the support angle steel 31 and the lower side of the support rod 30, which will affect the subsequent powder spraying quality and cause safety hazards.

[0031] As an optimization solution of the utility model, Figures 1 to 3 As shown, a support rod 32 is also provided on the base 20, one end of the support rod 32 is connected to the corner edge of the support angle steel 31 by line contact, and the setting direction of the support rod 32 is parallel to the side edge of the base 20. Preferably, the purpose of designing the structure of the support rod 32 is that when the bottom of the tower crane standard segment 10 contacts the support rod 32, the tower crane standard segment 10 only contacts the support rod 32 by line, thereby reducing the contact surface with the tower crane standard segment 10, reducing the subsequent paint touch-up area, and improving the product coating quality.

[0032] As an optimization solution of the utility model, Figures 1 to 3 As shown, a fixing bracket 33 is also provided at the top of the supporting angle steel 31, one end of the fixing bracket 33 is provided at the inner side of the top of the fixing bracket 33, and the other end of the fixing bracket 33 extends downward outside the fixing bracket 33 to form a curved structure, and the fixing bracket 33 is used to fix the main chord 11 of the tower crane standard segment 10. It should be noted that in order to reduce the contact surface with the tower crane standard segment 10, the utility model adopts the design of the supporting angle steel 31 and the supporting rod 32, but this design will affect the stability. In order to further increase the stability of the tower crane standard segment 10 when it is placed, the top of the tower crane standard segment 10 is clamped by the curved fixing bracket 33, so that the standard segment will not shake or shift in position during the painting process, keep the position stable, ensure uniform painting, and significantly improve the painting quality.

[0033] As an optimization solution of the utility model, Figure 1 and Figure 2 As shown, a plurality of legs 21 are evenly distributed on the bottom of the base 20. Preferably, the legs 21 are used to support the base 20. Preferably, there are also four legs 21.

[0034] As an optimization solution of the utility model, Figure 1 and Figure 2 As shown, a support pad 22 is disposed at the bottom of each support rod 30, and the support pad 22 is disposed on the inner wall of the base 20. Preferably, the support pad 22 is used to support the support rod 30. Preferably, there are also four support pads 22.

[0035] As an optimization solution of the utility model, Figure 1 and Figure 2 As shown, each support rod 30 has a hoisting hole 34 at the top. Preferably, the tooling of the present invention is hoisted into the powder coating line through the hoisting hole 34. Preferably, there are four hoisting holes 34.

[0036] As a specific embodiment of the present utility model, according to Figure 3 The use process of the utility model is described. When the utility model is used, two standard segments 10 of tower cranes are placed on the tooling, and the main chord 11 of the standard segments 10 of tower cranes is set on the support rods 32 on the two side edges of the base 20, and abuts against the support angle steels 31 at the bottom of the two support rods 30 on the two side edges, and the top of the standard segments 10 of tower cranes is clamped by the bent fixed bracket 33, and the two support rods 30 respectively support the two connecting rods 12 to position the standard segments 10 of tower cranes. The tooling is hoisted into the powder coating line through the hoisting hole 34, and shot blasting is performed before coating. The steel particles flow out through the gap between the concave surface of the support angle steel 31 and the lower side surface of the support rod 30. After the shot blasting is completed, coating is performed, and the powder coating line is left after the coating is completed.

[0037] Compared with the existing direct coating method, the utility model provides a special tool to assist in the coating process of the tower crane standard segments, so that the standard segments will not shake or shift during the coating process, maintain a stable position, ensure uniform coating, and significantly improve the coating quality. Compared with the existing direct coating method, the utility model can cooperate with the powder coating line, and transport the tool carrying the standard segments by hoisting, avoiding manual placement and removal of the standard segments, significantly improving the coating efficiency, and reducing the labor intensity and safety risks of the operators. Compared with the existing direct coating method, the utility model preferably uses four support rods. One tool of the utility model can hoist two standard segments at the same time. The standard segments enter the powder coating line together with the tool for powder spraying, which greatly improves the work efficiency of powder spraying of the standard segments.

For those skilled in the art, the utility model can have various modifications and changes.
